Love it!!
Super cute and work really well!! They are an unusual size though but you can easily buy the correct paper of the side. They are so far really sturdy and SO USEFULLLL. I love them so much and so aesthetic this is just what I need. However they are a little expensive when looking for the same thing on other sites you can find cheaper but only on like Temu and shein and the quality of this is probably much better. It’s so useful for reordering notes and i love it so much

Ideal size
This binder is just the right size. I had heard that b5 was a better size than a5 and a4 for the writing experience and it is. Bigger than a5, so you can get more words per page, but not as daunting as a4. I use this item to hold my current writing, as it only holds 25 sheets of paper, then transfer it to a bigger folder when i have completed it. At first I thought it was a bit expensive but the design is well thought out and the binding spine is lovely to use, so it's well worth the cost. It is sturdy enough to transport in my work bag and I have had no problems with it.

Another reason why Japanese stationery is irresistible
What a great little binder. The push-button opening on the rings is very clever and easy to operate. (Illustrated instructions on the back.) Forget the lethal metallic spring action and nipped fingers of the average British ring binder. It's a nice slim alternative to large-size rings – you could stash several in your bag – but it still manages to hold a lot of sheets. The paper is typically excellent Japanese quality, too, fountain pen friendly, and although this review isn't about the paper, you do get a few sheets included with it. This B5 format is for 26-hole paper, which is widely available in Japan but not in the UK, so you'll need to buy it (also available on Amazon) or invest in a Carl 26-hole punch to make your own. It's worth it because the extra holes means paper stays put. (And you can insert mini note sheets like the ones Maruman makes.) For just over a fiver and free shipping, this file is astonishing value. Time will tell if it stands up to rough handling, but my other Kokuyo products have proved to be pretty robust, so I expect this to be of the same build quality. Like most Japanese stationery, it's thoughtfully designed and a joy to use. The service was good too.

It’s so good
The quality is amazing and the price is so good too considering it’s for 3 binders and a stack of paper; if you buy just the notebook u gotta buy like stacks of loose kokuyo paper it’s on Amazon too overall it’s perfect for school especially for GCSEs or six form

Just what was required
My daughter really wanted these binders for school. They are a great idea as they take up much less room than even a slimline standard 2 ring binder but pages can still easily be clippped in and out. You can fold them back on themselves like a notebook so great for taking notes in class. Only downside is replacement paper is not so easy to come by and a bit more expensive.

Best choice for students study book
Perfect for revision notes. The only problem is the ring's sensitivity if you want to bend the book. You have to buy the paper separately. It has a really good page is also very compact and lightweight
